Abstract

A surgical anchor delivery device includes a shaft, a plurality of anchors disposed within the shaft, and a threaded rod disposed within the shaft and threadably engaged with the anchors. Rotation of the threaded rod advances the anchors toward the distal end of the shaft without rotating the anchors relative to the shaft. The delivery device may include an actuation mechanism configured to rotate the threaded rod. A method of delivering the anchors may include advancing the distal end of the shaft to a first location, rotating the threaded rod to advance a first anchor out the distal end of the shaft without rotating the first anchor relative to the shaft, repositioning the distal end of the shaft to a second position, and rotating the threaded rod to advance a second anchor out the distal end of the shaft without rotating the second anchor relative to the shaft.

First claim

What is claimed is:

1 . A surgical anchor delivery device, comprising:
an elongate shaft having a lumen extending to a distal end of the elongate shaft; a plurality of surgical anchors disposed within the lumen; and a threaded rod disposed within the elongate shaft and threadably engaged with the plurality of surgical anchors; wherein rotation of the threaded rod advances the plurality of surgical anchors within the lumen toward the distal end of the elongate shaft without rotating the plurality of surgical anchors relative to the elongate shaft.

2 . The surgical anchor delivery device of claim 1 , wherein the plurality of surgical anchors is prevented from rotating relative to the elongate shaft.

3 . The surgical anchor delivery device of claim 2 , wherein the lumen includes a noncircular cross-sectional shape.

4 . The surgical anchor delivery device of claim 3 , wherein each surgical anchor of the plurality of surgical anchors includes a noncircular perimeter shape.

5 . The surgical anchor delivery device of claim 2 , wherein each surgical anchor of the plurality of surgical anchors includes a tab extending radially outward from a peripheral edge of the anchor.

6 . The surgical anchor delivery device of claim 5 , wherein the elongate shaft includes a channel extending longitudinally along a wall of the elongate shaft and opening radially inwards;
wherein the tab is configured to extend into the channel when the plurality of surgical anchors is disposed within the lumen.

7 . The surgical anchor delivery device of claim 1 , wherein the plurality of surgical anchors is configured to slide distally within the lumen in response to rotation of the threaded rod.

8 . The surgical anchor delivery device of claim 1 , wherein rotation of the threaded rod is configured to advance the plurality of surgical anchors out of the lumen.

9 . The surgical anchor delivery device of claim 8 , wherein rotation of the threaded rod is configured to drive at least one barb extending distally from each surgical anchor of the plurality of surgical anchors into a target tissue.

10 . A surgical anchor delivery device, comprising:
a handle including an actuation mechanism; an elongate shaft extending from the handle, the elongate shaft having a lumen extending to a distal end of the elongate shaft; a plurality of surgical anchors disposed within the lumen; and a threaded rod disposed within the lumen and threadably engaged with the plurality of surgical anchors; wherein rotation of the threaded rod advances the plurality of surgical anchors within the lumen toward the distal end of the elongate shaft without rotating the plurality of surgical anchors relative to the elongate shaft; wherein the actuation mechanism is configured to rotate the threaded rod.

11 . The surgical anchor delivery device of claim 10 , wherein the actuation mechanism is configured to rotate the threaded rod in only a single direction.

12 . The surgical anchor delivery device of claim 10 , wherein the actuation mechanism is configured to shift between a starting position and an ending position;
wherein shifting the actuation mechanism from the starting position to the ending position advances only one surgical anchor of the plurality of surgical anchors out of the lumen.

13 . The surgical anchor delivery device of claim 12 , wherein after reaching the ending position, the actuation mechanism disengages from the threaded rod and the actuation mechanism is configured to return to the starting position while disengaged from the threaded rod.

14 . The surgical anchor delivery device of claim 12 , wherein after reaching the ending position, the actuation mechanism is configured to return to the starting position while simultaneously advancing a successive surgical anchor of the plurality of surgical anchors toward the distal end of the elongate shaft without rotating any of the plurality of surgical anchors relative to the elongate shaft.
